IMBROVEMENT m METAL v SLEIGH-RUNNER.

The Schedule referred to in these Letters Patent and making part at: the same To all whom it may concern:

Be itknown that I, DANIEL HOLDIMAN, of Waterloo, in the county of Black Hawk and State of Iowa, have invented a new and improved Sleigh-Runner, of which the following is a clear, full, and exact description, reference I being had to the accompanying drawing making a part of this specification, and in which Figure I is a perspective view of my runner.

Figure II is a view 'of' the steel shoe, made of springsteel. 7

The object of my invention is to provide a substantial sleigh-runner by combining steel with cast-iron, and furnishing a east-iron runner with a steelshoe, of spring-steel.

To enable others skilled in the art to understand and use my invent-ion, I will proceed to describe how I have carried ittout.

In the said drawing- I A is a cast-iron sleigi1-runner, cast with circular knees a a, and rests a a for the cross-beams.

On the bottom of the runners are cast thedovetailed shoulders r 'r, and diamond-pointed, so as to receive and hold snugly the shoulders b I) of the steel shoe.-

n n are slots or openings for the reception of the nuts 0 e, into which screw the bolts 0 c, to secure the shoe to the runner.

B is a steel shoe, with its ends or shoulders I b so pointed and beveledas to dovetail into the cast-iron runner at 'r 'r. \Vhcn thus fitted to the runner, the shoe is further secured in position by the bolts 0 0 passing through the shoe into the nutse e.

- Claim.

\Vhat I claim as my invention, and desire to secure by Letters Patent, is-

.The combination of a spring-steel shoe with a metal sleigh-runner, the spring-steel shoe being sprung into place and secured to the runner by means of a dovetail at each end, and intermediate bolts, substantially.
